Part of meal on salver, say (6)
I believe the answer is:
entree
'part of meal' is the definition.
(I've seen this before)
'on salver say' is the wordplay.
I cannot quite see how this works, but
'on' could be 're' ('on' can be mean 'with reference to') and 're' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for entree that I've seen before include "Something that provides access" , "Access - course at meal" , "Served after the fish and before the main course" , "Starter" , "No way-out" .)
